Chemical engineers design processes to ensure the most economical operation. This means that the entire production chain must be planned and controlled for costs. A chemical engineer can both simplify and complicate showcase reactions for an economic advantage. Using a lower pressure or temperature makes several reactions easier; ammonia for example, is simply produced from its component elements in a high-pressure reactor. This book offers arresting illustrations that set it apart from others of its kind. The author focuses on core topics of physical chemistry, presented within a modern framework of applications.
